Roles of Exogenous 5-Aminolevulinic Acid and Dihydroporphyrin Iron in Chlorophyll Precursor Synthesis and Chlorophyll-Related Enzyme Activities in Wheat Under Different Light Intensities

Agronomy
Aminolevulinic acid (5-ALA) and dihydroporphyrin iron chelates (DHFe) play roles in plant growth regulation under normal and stressful conditions. However, definitive data on their roles in regulating chlorophyll synthesis in wheat are lacking.

Lil3 Assembles with Proteins Regulating Chlorophyll Synthesis in Barley

PLOS ONE, 2015
The light-harvesting-like (LIL) proteins are a family of membrane proteins that share a chlorophyll a/b-binding motif with the major light-harvesting antenna proteins of oxygenic photoautotrophs. LIL proteins have been associated with the regulation of tetrapyrrol biosynthesis, and plant responses to light-stress.

White Clover Residues Inhibit the Promoting Effect of Funneliformis mosseae on the Growth and Photosynthetic Physiology of Trifoliate Orange

International Journal of Fruit Science
In citrus orchards, the impact of incorporating cover crop residues into soil on mycorrhizal symbiosis remains unclear. This study aimed to analyze the effects of applying dried white clover residues to the rhizosphere of trifoliate orange (Poncirus ...

The HY5-PIF regulatory module coordinates light and temperature control of photosynthetic gene transcription [PDF]

, 2014
The ability to interpret daily and seasonal alterations in light and temperature signals is essential for plant survival. This is particularly important during seedling establishment when the phytochrome photoreceptors activate photosynthetic pigment ...

Comparative Proteomic Analysis of Flag Leaves Reveals New Insight into Wheat Heat Adaptation

Frontiers in Plant Science, 2017
Hexaploid wheat (Triticum aestivum L.) is an important food crop but it is vulnerable to heat. The heat-responsive proteome of wheat remains to be fully elucidated because of previous technical and genomic limitations, and this has hindered our ...
